I downloaded nemisis's kernel 1200 OC and -50UV. it says the kernel is already overclocked. Does that mean i dont have to use setcpu? I never used any of these overclocked or undervolted kernels before. What instances do i need setcpu for?
You need to use setcpu. Its also useful for when u want to use different kernel governers or profiles under certain conditions.

ok so then the enderst special oc 1200 mhz uv by -50mv kernel is basically useless unless i use that app then (minus the UV)? also what are the chances im gunna fry my processor if i keep this overclock kernel for everyday use?
Edit: also how hot is too hot for a battery to get? aka whats a normal range? also after heavy use (like after playing angry birds or tank hero)?
The battery in our phone (cobalt li-on) should never go above 130c. At above 150c you going to get thermal runaway and have a dead or exploded battery.
For a good article on lithium batteries see: www.buchmann.ca/article28-page1.asp

The profiles are NOT compatible with Galaxy S phones, at least the Fascinate. Some may work for some people alright, but most people experience many different problems, I myself have problems with the profiles. I recommend against using them. Just use it for the governor/overclock.

SEARCH XDA AND GOOGLE. There are prolly a dozen threads on CPU clocking for your phone. (I'm assuming you mean underclocking, right?)

download a oc/uv kernel then install voltage control from the marker, I suggest eugenes dead horse kernel but that's just me.

You can start by posting in the correct forum. Q&A... General...
Yeah, that would be a good start.
Yes post in Q & A next time please.
There are many apps on the market that will do this. Under-volting is just lowering the voltage to the cpu. The voltage standard setting is set based on the voltage that will work best for all manufactured cpus in a unit. Most of these chips are "low-bid" so the Q/C is not that accurate, so they set the voltage a little higher to make sure they always perform. Most of the tech savvy people know they can lower that setting....... and do so to lower temp and add to battery life.
Underclocking is something else entirely That is the cycle clock speed......... 2 different animals.

Hey all,
I've been using CPU Master on my Rezound since I rooted it. But I used to use SetCPU on my Dinc. My question is, which do you prefer? I have the free version of CPU Master and paid for SetCPU.

I paid for setcpu too but I was having issues so i tried cpu master before buying it. least try cpu master and if it setcpu is better then get your refund

Under/overvolting and io scheduler selection is really the only things it offers in the paid version. I've used setcpu on my og droid and on my incredible, but I bought CPU master when I got my rezound and I actually prefer it over setcpu. One thing I like is that the profiles are already set up for you, all you have to do is enable or disable them.
I've had really good luck with CPU tuner
Free and has a lot of features.
Under 8 posts for me so I can't post the stupid link... Just search for it in the market and check out the reviews.
If I wanted to undervolt, how far under should I go? My kernels have always handled voltage for me lol

this varies from person to person. needs to be scaled right while you're finding the sweet spot. I do -25 for each frequency. run it for awhile to see if you get a random reboot or lag and just reverse what you did. I did -25 for each until I have time to drop them further

Thanks very helpful. Seeing how well the undervolting goes before I make my final decision
Sent from my ADR6425LVW using Tapatalk
Depends upon the kernel. I found SetCPU worked better with stock and Ziggy's kernel. With dsb's smartass v.2 kernel, I find CPU Master works better.
Yeah I know that each phone individually responds differently to cpu/voltage changes. The dinc i had before this would take any frequency and kernel would throw at it. However underclocking/volting on my Rezound almost always ends in fc's
Sent from my ADR6425LVW using Tapatalk
I use SetCPU mostly if I can... Provides more information than CPU master pro, I have both... The only thing that CPU master pro does that SetCPU doesn't is change voltages, in a crappy way though. I don't go through every clock to change them, that takes way too long. Instead I use incredicontrol to change them all simultaneously... I've never had problems with one over the other. They have both worked for me on all the kernels for this phone.
setcpu
I'm using Ineffabilis v1.0 with Ziggy's kernel. SetCPU has worked for me with no issues. I haven't tried CPU Master but I guess I haven't had the need to cuz SetCPU is working for me. I just don't completely get the whole undervolting. I understand the concept but don't know how to apply it with SetCPU, if that's even possible.

I haven't tried to play around with voltages on the rezound, but on my tbolt I could drop voltages 100 each and be fine, but couldn't run at 1.8 no matter what I tried.

You can't change voltage with SetCPU. CPU Master can. Correct me if I'm wrong but kernels can also effect voltage. Amirite?

There's no overclocking or voltage adjustments available with the stock kernel. You can change governor and I/O scheduler but that's it for now.

What is the purpose of I/O? Right now I'm using setcpu with governor set to on demand and a special profile set so when my screen goes off the CPU turns down. My battery life still totally sucks lol

Ah yeah, I haven't used setCPU since I had my incredible, but with those kernels you couldn't change things like I/O scheduler so I didn't know if you could with the right kernel. I definitely prefer voltage control and it seems to just work best with galaxy S phones. There's also Pimp My CPU but I haven't tried it yet.
You can read about I/O schedulers, but usually the default setting is best. You're possibly not really saving battery with a screen off profile that throttles your CPU. I've seen it postulated that with the phone being able to scale up the CPU when the screen is off, it can accomplish whatever it needs to faster, and therefore get to deep sleep faster (where your phone is consuming the least power). Not really sure if it's true, but it sounds plausible. Also, I've seen that glitch V14 has a deep idle feature, which I think in theory at least, is supposed to be even more efficient than deep sleep. I don't know much about it though or how well it's working on the fascinate.
So far, my battery life seems to have taken a bit of a hit with ICS too, but I'd like to put it through a few more charge cycles before making too much of a judgement.

Well, I'm not sure if that was a question or not but as far as I know you can't flash the kernel because of our wonderful locked bootloaders...
If you were to use the search function, you would see that there are modules and scripts available to overclock our CPUs. Our processors are already factory overclocked 200Mhz, the maximum I have been able to reach is 1.3Ghz
I was looking to under volt to save battery

You can do that as well
Sent from my XT910 using XDA
is it possible to undervolt by only setting it in one app?
without too much trouble, i'm not good in flashing files etc.
As far as I know, the only way is using scripts, and you can adjust the clock frequency in say.. SetCPU. But the voltage settings are only available in the script itself, if you check this post you can see there are scripts already made for under clocking / under volting.
I want to know what's the safe overclocking maximum and governor . I also want to know what's the maximum safe temperature? Is 50c' as a maximum safe? Thanks for your help.
Sent from my SK17i using xda premium
theres no such tthing as safe oc.
each and every cpu had different characteristic thus different capability when it comes to oc. what might works with others might just hardbrick yours. you just need to experiment yourself. do note thats its dangerous. earlier one guy already fried his phone when oc to 1.8ghz+playing gta3.
and for me personally 45c feels too hot already.

I know what you mean. You are right of course. Mine is overclocked to 1.3ghz governor smartassV2 and the max temp for overclocking is my problem now. I can't decide what is the max temp at which the phone should go back to 1ghz . Do you think 45c' as a maximum safe?

then use any app that can create profile to automatically lower cpu freq based on temperature eg cputuner or setcpu.

I'd say 45° MAX. Or even less. And still you can't be 100% sure you won't have any problem.
